Question

PHP编码的新手帮助我。这是我的代码：

echo "<td id=\"row\" align=\"center\">" . $row['id'] . "</td>";
echo "<td id=\"title\" align=\"center\">" . $row['Title'] . "</td>";
echo "<td id=\"prodname\" align=\"center\">" . $row['ProductName'] . "</td>";
echo "<td id=\"amt\" align=\"center\">" . $row['Amount'] . "</td>";
$amt = $row['Amount'];
echo "<td id=\"row\" align=\"center\">" . 
     "<select id=\"testing\" onchange=\"GetSelected (this,$amt)\">
        <option value=\"100\">100g</option>
        <option value=\"250\">250g</option>
      </select>" . "</td>";
echo "<td>" . "<input type=\"button\" value=\"Add\">" . "</td>";

点击“添加”按钮后，我需要将行值存储在数组或变量中。

Answer 1

你可以这样编码

<form name="frm" method="POST" action="">
 <table>
  <tr>
echo "<td id=\"row\" align=\"center\">" . $row['id'] . "</td>";
echo "<td id=\"title\" align=\"center\">" . $row['Title'] . "</td>";
echo "<td id=\"prodname\" align=\"center\">" . $row['ProductName'] . "</td>";
echo "<td id=\"amt\" align=\"center\">" . $row['Amount'] . "</td>";
$amt = $row['Amount'];
echo "<td id=\"row\" align=\"center\">" . 
     "<select id=\"testing\" onchange=\"GetSelected (this,$amt)\">
        <option value=\"100\">100g</option>
        <option value=\"250\">250g</option>
      </select>" . "</td>";
echo "<td>" . "<input type=\"SUBMIT\" value=\"Add\">" . "</td>";
  </tr>
 <table>
</form>

现在您可以将数组设为 $ _ POST 或 $ _ REQUEST

Answer 2

我希望以下代码可以帮助您解决问题。

将此代码放在PHP脚本中

 <? php
   if ( $_GET["reg"] == "suc" )
   {
     $row['id']=$_GET["id"];
     $row['Title']=$_GET["title"];
     $row['prod']=$_GET["prod"];
     $row['amount']=$_GET["amt"];
   }
   else
   {
   echo "try again";
   }
  echo "<form action=\"?reg=suc\" method=\"GET\">\n";
  echo "Id: <input name=\"id\" ><br />\n";
  echo "Title: <input type=\"text\" name=\"title\" ><br />\n";
  echo "Productname: <input name=\"prod\" ><br />\n";
  echo '<input type="checkbox" name="amt" value="100" >';
  echo '<input type="checkbox" name="amt" value="250" > ';
  echo "<input type=\"submit\" name=\"Add\">\n";
  echo "</form>\n";
 ?>

如果单击“添加”按钮，这些值将存储在数组中你可以用POST方法代替GET以隐藏的方式发送这些值!!!
